SMOKE-CONSUMING FURNACE.

SPECIFICATION formingpart of Letters Patent No. 412,659, dated October 8, 1889. Application filed December 15, 1888- Serial No. 293,670. (No model.)

To all.whom it nwy concern:

Be it known that I, WILLIAM PERRY, of the city, county, and State of New York, "a citizen of the United States, have invented certain new and useful Improvements iii Smoke- Oonsumiu-g Furnaces, of which the following is a specification. I

The object of my invention is to provide a new and improved smoke-consumin g furnace,

- to in which the smoke-consuming device is dura- 2o tional plan view of the same.

Similar letters of reference indicate corresponding parts.

Some distance from the rear wall A of the furnace B, I provide an additional transverse wall 0, the top of which is higher than the top of the wall A. An inclined arch or floor D extends from the top of the wall 0 to the top of the wall A. If desired, this wall may be made of metal, but an arch is preferred.

This floor or arch D is provided with aseries of apertures through which pipes E are passed,

the upper ends of which project about an inch or so above the upper surface of the floor or arch D, the lower ends of said tubes 3 5 projecting into the chamber below said floor.

The lower ends of the pipes are provided with apertures through which air can enter. The

bottoms or lower ends of said pipes are open for the same purpose.

0 provided with a collar F, resting on the top of Said pipes are each the floor D, for the purpose of holding the tubes in place and preventing their dropping through the apertures in the floor or arch D. Any other suitable device may be provided for the same purpose. The furnace Bis provided with the usual gear-bar H. The flame and products of combustion of the fire on the grate-bars H pass over the upper ends of the 7 tubes E and heat them. The air passes through suitable openings in the wall A into the chamber below the arch or floor D and passes up through the hot pipes E, whereby it is heated. This hot air, coming in contact with the smoke, cinders, &c., passing over the floor D in the upper end of the pipes E, consumes said 'cinders and smoke at once. The pipes E'are not apt to become clogged, but should this nevertheless occur they can be cleaned very easily.

Having thus described my invention,l claim as new and desire to secure by Letters Patent The combination, with the rear wall of a furnace having an opening or openings, of an additional transverse wall at some distance back of the same, an arch or floor connecting said walls, and a series of pipes passed through said floor or arch, which pipes are open at the top and bottom, the upper ends of the pipes projecting a short distance above the top of said arch or floor, and the lower parts of the pipes being perforated and in direct communication with the space formed below said arch or floor, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

WILLIAM PERRY.
